CRS226 - Poe-in Juniper

I just purchased a CRS226-24G-2S+RM and I am trying to power it via poe-in off a juniper switch. Juniper provides power off pin (1,2 for negative / 3,6 for positive), and according to the wiki http://wiki.mikrotik.com/index.php?title=Manual:TOC/MikroTik_POE_in_compatibility_table it should work with a standard crossover cable, but im getting no joy.

Does anybody have any insight on this?

mikrotik only supports passive POE
